ISSUE BACKGROUND

35-40% of channel capacity is lost due to sediment deposition upstrem soilerosionfarmingactivitiesdownstrem

6500-7000 t of garbage are produced in the river every day, the main source of which is household garbage

30-70 cm of water depth on municipal roads during flood season

12 centimetres of land is sinking every year in Jakarta, especially in northern parts of the city

River Problem Location

More than 60 percent of Jakarta's residents depend on groundwater.This provides nearly two-thirds of the city’s water consumption, around 630 million cubic metres out of 1 billion m3/year.

The site is located in the northwest of Jakarta, adjacent to Kali Canal. It is a kampung with a history of more than 60 years.

The study found that the Kali River has been widened in 2015, resulting in the forced demolition of more than 300 families in the surrounding area and moved to the new residential community along Daan Mogot Street, nearly 7km away. Since many residents were unwilling to be demolished and did not want to move to new tall buildings, this issue intensified the conflict between the government and residents, leaving the remaining people still living by the Kali River without a sense of belonging. At the same time, in Jakarta’s 2030 plan, the road along the Kali River will be rebuilt and widened to become a secondary road, which means their home will face demolition as well. Therefore, it is inevitable for them to leave, and, Jakarta ’s violent resistance to relocation shows that new living conditions must be carefully considered. This project aims to provide a new living environment that can provide them with the sense of belonging. The new residence will enable them to adapt to the high-rise building and participate in social production, resulting them treating it as home rather than a temporary residence. Through field investigation, it is found that in kampung, people manage themselves through the RT and RW system, which is one of the reasons why they do not want to move. Secondly, their income comes from each other, only a few people are factory workers, more than 40% of the households are engaged in informal sales activities like street vendors. In addition, it has many outdoor activities. And Kali River as their public area has become part of their daily lives. This design will reconsider people ’s resettlement issues, making the site close to the river, and create different landscapes by introducing water from the river into residential and agricultural area. For better agricultural production, it is determined the most suitable cultivated land through sunshine analysis. And rivers introduced will provide the irrigation. In terms of living environment, the river will flow along each building to give people the familiar feeling of still living on the banks of the river. After satisfying self-sufficiency, they can obtain the sense of ownership and belonging again. At the same time, using farming activities as a catalyst can enhance sense of community, financial support, education, and branding.

Issues In Relocation

From Kampung places to Highrise building

Compared with the rich activities in the kampung, the new settlement will meet the needs of people to communicate, and also affects the income of the shop.
